0D dinuclear manganese(Ⅱ)coordination compound and 1D chain manganese(Ⅱ)coordination polymer,namely[Mn2(μ-L)(phen)4]·4H2O(1)and{[Mn2(μ5-L)(phen)2]·H2O}n(2),have been constructed hydrothermally using H4L(... 0D dinuclear manganese(Ⅱ)coordination compound and 1D chain manganese(Ⅱ)coordination polymer,namely[Mn2(μ-L)(phen)4]·4H2O(1)and{[Mn2(μ5-L)(phen)2]·H2O}n(2),have been constructed hydrothermally using H4L(H4L=2,3,3΄,4΄-diphenyl ether tetracarboxylic acid),phen(phen=1,10-phenanthroline),and manganese chloride at 120 and 160°C,respectively.The products were isolated as stable crystalline solids and were characterized by IR spectra,elemental analyses,thermogravimetric analyses(TGA),and single-crystal X-ray diffraction analyses.Single-crystal X-ray diffraction analyses revealed that two compounds crystallize in the triclinic or monoclinic system,space group P1 or P21/c.Compound 1 discloses a discrete dimeric structure,which is assembled into a 3D supramolecular framework through O-H…O hydrogen bond.Compound 2 has a chain structure.Structural differences between compounds 1 and 2 are attributed to the different reaction temperature.Magnetic studies for compound 2 demonstrate an antiferromagnetic coupling between the adjacent Mn(Ⅱ)centers. 展开更多
